To all whom it 17mg concern.-

Be it known that I, THoMAs FITZGERALD, Jr., a citizen of the UnitedStates, residing at Fredonia, in the county of Chautauqua and State ofNew York, have invented a new and useful Improvement in Machines forPouring Filling Material in Orevices, of which the following is aspecification.

In some pavements the paving bricks or blocks are laid loosely on a bedof sand or the like and melted pitch, tar, cement, or analogous materialis poured into the crevices between the bricks or blocks and acts whenset to permanently bind or cement the bricks or blocks together. Up tothe present time it has been customary, so far asIam aware, to pour themelted pitch or other filler into the crevices by hand with a spoutedcan or pot. This operation is slow and tedious, and it is only possibleto pour the filler into one crevice at a time, and it is also wasteful,as it requires considerable care not to pour the pitch on the surface ofthe bricks or. blocks, and the ordinary laborer will not take the painsnecessary to prevent such waste. The cost of the filling thereforeamounts to a very considerable part of the cost of the pavement.

This invention relates to a portable machine or device for pouring thefilling material into the crevices of the pavement, and has for itsprimary object to produce a pouring machine or device which can beoperated with ease to rapidly fill the crevices without scattering orwasting the filling material.

Other objects of the invention are to provide the machine or device withmeans for guiding the pouring spouts or nozzles accurately along thecrevices as the machine is moved over the pavement, to provide simpleand easily-operated means for controlling the flow of the fillingmaterial, and to equip the machine or device with means for keeping thefilling material in the proper liquid condition, so that it will readilyflow.

The pouring machine or device comprises a tank or receptacle for themelted pitch or filling material, which is mounted on wheels or a truckof some sort, enabling it to be moved over the pavement with facility,and is provided with one or more pouring spouts or nozzles and guidemeans which travel in the crevices of the pavement and automaticallyhold the discharge ends of. the nozzles over the crevices in such manneras to direct the streams of filling material into the crevices andprevent the material from flowing over the surface of the pavement.Regulating-valves are provided for controlling the flow of the fillingmaterial and also means for heating the spouts or nozzles and the tankto maintain the filling material in the proper condition of liquidity.

1n the accompanying drawings, consisting of two sheets, Figure 1 is alongitudinal sectional elevation of a pouring-machine embodying theinvention. Fig. 2isa plan view thereof. Fig. 3 is a transverse sectionalelevation thereof in line 3 3, Fig. 1. Fig. 1 is a front elevation ofthe lower part thereof, showing the nozzle-guiding means.

Like letters of reference refer to like parts in the several figures.

A represents a tank, vessel, or receptacle for the melted pitch, fillingliquid, or other material adapted to flow or pour in streams, and Brepresents a truck or wheeled support on which the tank is mounted, soas to be readily rolled or moved about. In the construction shown in thedrawings the truck consists of two wheels journaled on an axle b, whichpasses through and supports the tank, and operating-handles 0, connectedto the axle by side bars 0. The tank is of cylindricalform andpreferably has atits bottom a transverse depressed portion or trough D,provided with depending discharges )outs (Z. One or more spouts may beemployed; but the tank is preferably provided with several spouts toproduce a number of streams, so that several crevices can be filledsimultaneously. A tank and truck or portable support of any othersuitable construction could be used instead of that shown in thedrawings.

In order-to direct the streams flowing from the spouts and cause them toenter the crevices as the device is pushed along over the pavement, eachspout has a movable or flexible extension discharge end or nozzle E,which extends nearly to the surface of the pavement and has a dischargeorifice of a size and shape to properly pour the material into thecrevices between the bricks or blocks. In the construction shown in thedrawings the nozzle or spout extension consists of a tube having aflaring or funnel shaped upper end surrounding the lower end of thespout d and an elongated narrow exit-orifice c and is supportedindependently of the spout, so as to be movable relative thereto by anarmf, secured to a leg or support F, depending from a bale IIO orbracket f, which is secured to the side I The pitch or filling materialis ordinarily bars of the truck. The several nozzles are supported by asmany armsf and legs F, the legs all being attached to the bracket f. Thelegs are preferably made of spring or flexible metal and are provided attheir lower end with guide devices Gr, adapted to enter and travel alongin the crevices between the bricks or blocks as the machine is movedover the pavement. Wheels with beveled edges journaled on the lower endsof the legs are preferably employed for the guide devices. Such wheelsact to spread or separate the bricks or blocks slightly, thus openingthe crevices and better insuring the entrance of the filling materialbetween the bricks or blocks. The legs F are flexible enough to allowthe guide-wheels to follow the irregularities of the cracks and alwayshold the exit ends of the spouts or nozzles directly over the crevices,but yet are sufliciently stiff to cause the machine when pushed alongthe pavement to follow the line of the cracks. Thus the guide-wheelsperform the double function of guiding the machine and holding thenozzles over the crevices of the pavement. The described construction ofthe nozzles and guide means is deemed desirable; but other means forguiding the machine and shifting the discharge ends of the spouts ornozzles, so as to direct the streams of filling material into thecrevices, could be used.

Valves H, of some suitable construction, are employed for controllingthe flow of the material from the tank. The valves shown consist ofconical plugs or stoppers located in the tapering spouts and connectedto the lower ends of rods it, which are adjustably secured at theirupper ends, as by clamp-nuts h, to the cross-bar e' of anoperating-lever I, which is pivoted on the upper end of the tank. Thelever is provided with any suitable means such, for instance, as aclamp-bolt K, working in a slotted post on the tankfor releasablyholding it in different positions. By adjusting the valve-rods on thelever I the several valves can be located in the same relative positionin the several spouts, and by raising and lowering the lever the valvescan be operated to regulate and start and stop the flow of the materialas desired.

L, Fig. 1, represents a burner arranged beneath the tank adjacent to thedischarge spouts or nozzles for heating the latter and the tank to keepthe pitch or filling material at the proper temperature to readily flow.The burner is supplied with liquid or gaseous fuel by a pipe Z from areservoir Z, supported on the tank or other suitable part of the machineand is preferably inclosed by a fire box or shield M, surrounding thedischarge-spouts and trough to confine the burner-flame about theseparts and the bottom of the tank. One or more burners of any known orsuitable construction may be used, as found necessary.

melted before it is placed in the tank, and the burners are only for thepurpose of keeping the material hot and in a liquid condition whileusing the machine and for melting the small amount of material which mayharden in the tank and spouts when the machine is not in use. As thevalves H are located in the discharge-spouts in the vicinity of theburner the pitch or filling material will not harden about them andprevent the operation thereof, and as the spouts are relatively shortand of large diameter there is little liability of the pitch hardeningand clogging them.

0 represents a strainer in the upper part of the tank through which thematerial is poured into the tank for the purpose of removing any solidparticles or foreign matter which could clog the discharge-nozzles orinterfere with the operation of the valves.

While the machine described is designed, primarily, for pouring meltedpitch or analogous viscous liquid filling material in the crevices ofbrick or block pavements in the construction thereof, it is notnecessarily limited to such use, but may be employed for pouring otherliquids or materials in streams for other purposes.
